Summary: The application of hydrogen is a promising way to alleviate global energy pollution. However, the current electrocatalytic hydrogen evolution using noble metals is limited by low kinetics. Therefore, it is urgent to develop non-noble metal electrocatalysts with enhanced efficiency and environmental friendliness. In this study, two-dimensional ultrathin CoP networked materials were successfully synthesized and showed high current density and cyclic stability, suggesting their potential applications in various electrochemical energy conversion and storage fields.

Summary: A hierarchical CoP-Ni5P4 nanosheet array self-supported electrode (CoP-Ni5P4/NF) for water splitting was successfully constructed by a simple MOF calcination method. CoP-Ni5P4/NF exhibited outstanding performance for overall alkaline water splitting, with a potential of only 1.47 V at 10 mA cm(-2) and exceptional stability beyond 50 hours. The construction of the hierarchical CoP-Ni5P4 nanosheet array self-supported electrode increased the exposure of active sites, enhanced conductivity and stability, while the interfacial effect of CoP-Ni5P4 effectively regulated the electronic structure and reduced the adsorption energy of intermediates, thereby improving water electrolysis kinetics. This work provides fresh impetus to the design of MOF-derived two-dimensional heterogeneous catalysts for overall water splitting.

Summary: This study developed a low-cost and high-performance electrocatalyst for water splitting, which is crucial for hydrogen production. By introducing oxygen-deficient CeO2 nanoparticles on (Ni, Co)2P nanosheets, a high-performance hydrogen and oxygen evolution reaction bifunctional electrocatalyst was created. The introduction of defective CeO2 modulated the electronic structure of the CeO2@(Ni, Co)2P/NF interface, resulting in a synergistic effect that promotes the HER/OER reaction in alkaline water splitting.

Summary: Constructing self-supported electrocatalysts is important for enhancing the performance of water splitting. In this study, a bimetallic phosphide CoNiP grown on a micro-sized porous nickel substrate showed low overpotentials for hydrogen and oxygen evolution reactions. The micro-sized porous nickel substrate provided a large surface area for active material loading, and the hierarchically porous structure facilitated mass transfer in the electrocatalytic reaction. The CoNiP/MP Ni electrocatalyst achieved ultra-low overpotentials and stable operation, making it a promising candidate for water splitting.

Summary: Hydrogen, a sustainable and high-energy-density green energy, can be produced through hydrogen evolution reaction via electrocatalysis. However, the scarcity and cost of platinum (Pt) limit its application in hydrogen evolution reaction. Therefore, the research focus has shifted to non-Pt/low-Pt electrocatalysts. Amorphous metal phosphide electrocatalysts, with their long-range disordered but short-/medium-range ordered structures that contain abundant active sites and adjustable electronic structures, have shown significant electrocatalytic activities in hydrogen evolution reaction.
